Homework Help: Which formula?

  1. May 9, 2006 #1
    How do i calculate the power transmitted by a clutch at a particular speed with a coefficient of friction between the shoes and drum?
    I can't find any reference in my text book.:confused:

    I can't say that I have any other references than those for disc or conical clutches. Do either of these meet your criteria?

    I can add to Fred's offer of help with disc, conical, multi-plate and centrifugal clutches....

    Thank you :-)

    The problem involves a centrifugal clutch

    The question is..

    Determine the power transmittedby the clutchwhen speed of rotation is600rev/min. Co-efficient of friction is 0.3.

    I have values for force and radius, i just don't know what formula to use or how to calculate the power :cry:

    Without having a book in front of me, I would venture that you calculate the torque that is transmitted due to the frictional force and then use the torque and speed to calculate the power.

    Coef of friction

    Yes i thought that would be the way but, where does the coefficient of friction fit in?
